BOSTON - ABC News reports an unsolved 2011 triple murder case in Boston, described as one of the most gruesome killings in the area, has now been re-opened as authorities try to confirm whether the crime was connected to accused Boston Marathon bomber Tamerlan Tsarnaev.
The three male victims, one of them Tamerlan's former roommate, were found with their throats slit, nearly decapitated and covered in marijuana in a Waltham, Massachusetts apartment near the anniversary of the September 11 attacks.
Tamerlan had been training with one of the victims for a career in mixed-martial arts.
The victims' families have asked officials to look into the suspect's connection because they believe Tamerlan had something to do with it.
26-year-old Tamerlan died in a gun battle with police during the search for the Boston Marathon suspects last Friday morning while his brother and suspected partner in the bombings, 19-year-old Dzhokhar, escaped.
Dzhokhar was finally taken into custody Friday night.
Boston and nearby cities were on lockdown Friday as several branches of law enforcement, including FBI, combed through the area to find the surviving suspect.
U.S. authorities are also searching for possible links between the Tsarnaev brothers and 2 Kazakhstan nationals arrested on Saturday.
Those men - whose names have not been released - once lived in the same town as the bombing suspects.
The Kazakhstan nationals were arrested after violating the U.S. Vvsa regime.
